My invention relates to a burner or heater and may for example beemployed with heaters or burners or stoves for burning a flui dhydrocarbon. One object of my invention is to provide a heater orcombustion umt wh ch is demountable, and in particular, from which themixing chamber may readily be removed. Another object is the provisionof ready means for taking down or cleaning the mixing chamber. Anotherobject is the provision of improved means for admitting the air supplyto the mixing chamber. ther objects will appear from time to tlme 1n thecourse of the specification and claims.

I illustrate my invention more or less diagrammatically in theaccompanying drawin ,wherein.

igure 1 is a vertical section; and

Figure 2 is a vertical section through a variant form of my device.

Like parts are indicated by like symbols throu bout the specificationand drawing Re erring to the drawing, A generally 1ndicates a radiationand combustion chamber, which may for example be cylindrically walled,but the form, size and proportion of which may be varied to suit varyingconditions. A indicate a bottom portion of the member A, both eingherein shown as of '30 sheet metal and secured together as at A WhereasI have indicated bolts or rivets, it is clear that any other suitablesecuring means ma be employed.

ecured to the member A are a plurality 85 of supporting feet B, hereinshown as provided with inwardly projecting integral flanges B withbosses B provided with screwthreaded apertures B Adapted to penetrateand closely fit in the 40 central aperture A of the bottom member A isthe cylindrical wall member C, the lower and outwardly projecting flangeC of which is adapted snugly to engage the bottom of the member A It mayfor example be locked in position by the locking brackets G which areapertured as at C to permit the passage therethrough of the securingscrews C screwthreaded into the aperture B. 0 indicates an suitablemanual memher for locking an unlocking rotation of the screw C. Themember C is provided with an outer extension 0 abutting against themember B and an inner extension C abutting against the flange C It willbe understood that when the screws are rotated into locking position theflange C is firmly clamped against the bottom of the member A insubstantial air-tight relationship.

Mounted upon or, if desired, formed integral with the cylindrical wallC, is an innor apertured wall D. It is connected to the wall C, as anupper outer extension or flan e D. D indicates a bottom, which may beintegral with the wall D. The Wall is provided with any suitableapertures, for example the primary air supply apertures D distributedabout the lower and intermediate portion of the wall D, and thesecondary air apertures D, positioned adjacent the upper edge of thewall D. The apertures D may if desired be upwardly as well as inwardlyinclined, as shown, so that the secondary air supply is directedupwardly as well as inwardly about the mixture of'air and fuel risingupwardly from the interior of the mixing chamber formed by the wall Dand the bottom D E indicates a fuel supply pipe extending from anysuitable source of fuel. It may for example be controlled b the valve Eillus trated with the manua control handle E The pipe E ma be connected,as by the elbow E"*, with t e vertically extendlng ipe E incommunication with the interior 0 the mixing chamber. Preferably itterminates somewhat above the bottom D and may be locked in relation tothe bottom, as by the securing and spacing nuts E E, with which it ma bein screwthreaded relation.

Re erring to the form of Figure 2 I illustrate a unitary bottom member Gto which the legs Gr may be secured or with which they may be unitarilyor integrally formed. Gr indicates an interior positioning flange aboutthe exterior of which the c llnder or wall A may be slipped. G and 4indicate inner, for example annular flanges or upward projections fromthe bottom G, provided with exterior vertically horizontally walledseats G G.

H indicates an outer and H an inner wall for a mixing chamber, seatedrespectively on the seats G G. It will be noted that the wall H is blanklike the wall G of Figure 1, whereas the wall H is provided withaperturee D and D, similar to those emplo ed in connection with theinner wall D of igure 1. H generally indicates a dgap or ring seatedupon the walls H H an positione for exam le by the downwardly extendingannular flan H and the downward enlar ment H indicates an upwardly aninwardly inclined face of the enlarged portion H which terminates in thecentral aperture The bottom G is a rtured as at J, preferably a seriesof rat er large apertures, .to admit air into the space between thewalls H and H. It will be realized that as to both forms of the deviceany suitable exhaust aperture or flue or draft arrangement may be madefor the combustion and radiation chamber formed by the wall A.

It will be realized that whereas I have described and shown a practicaland operative device nevertheless many changes might be made in thesize, sha e, number and disposition of parts without eparting from the sirit of my invention. I therefore wish my escri tion and drawing to betaken as in a broad sense illustrative and diagrammatic rather than aslimiting me to my specific showing.

The use and operation of my invention are as follows:

My device is adapted for example to types of burners wherein fluidhydrocarbons, for example liquid hydrocarbons, are burned byhydroxylation. That is to sa a liquid hydrocarbon may be introduce tothe space between the wall D or H, where it is mixed with prima airentering through the apertures D. he rimary mixture so formed risesupwardly t rough the mixing chamber and is penetrated by or surroundedby or .mixed with a secondary air supply entering through the aperturesD. -The mixture so formed is burned in the upper ortion of the mixingchamber or above t e mixing chamber within the wall A. This combustion,largely above the top of the mixing chamber, heats the space within thewall A, whence the heat is radiated. The combustion -also takes placesufliciently close to the mixing chamber to cause vaporization orgasification of the liquid hydrocarbon supply along the line E, and thisgasified hydrocarbon, first mixed with the rimary air supply, and thenwith the secon ary air suply, is burned off in the combustion andrasiation chamber. The mixing chamber being housed within the wall A, issubstantially insulated from the cold outer air, by the heated productsof combustion within the wall A. The air as it flows up within the wallC or the base G. The numbero factured is small and the device is easily,

quickly and cheaply assembled.

I claim:

1. In a stove for use with fluid hydrocarbons, a radiation chambermember and a supporting base thereforila mixing chamber memberpositioned wit in said radiation chamber, said member including anouterwall extending upwardly from an aperture in the bottom of said baseand removably positioned in relation to said base, and an inner wall suported upon and spaced inward- 1y from said outer wall, said inner wallineluding portions extending outwardly for contact with the upper edgeof said outer wall, said inner wall being pierced by a plurality of airapertures, the space between the outer and inner walls being accessibleto an exteriorair supply, and a fuel line extending to the space withinthe inner wall, said inner wall having associated with it a bottomclosure portion independent of said base and supported upon said innerwall.
